Uppsala researchers have succeeded in designing a molecule that inhibits coronavirus replication and has great potential for the development of drugs suitable for the treatment of COVID-19. This molecule is effective against both new mutants and previously identified coronaviruses.The research paper was published in Journal of the American Chemical Society..


The new coronavirus has killed more than 5 million people. Antiviral drugs could have saved many lives, but this type of treatment was not available in the medical system. During the pandemic, researchers around the world tried to find medicines, but it often takes a long time to develop new medicines.

During the first months of the pandemic, researchers were able to determine the structure of the coronavirus and how it works at the molecular level. One of the viral enzymes has been identified as a promising target for drugs, a successful strategy in other viral diseases such as AIDS.The idea is to design a molecule that has the ability to recognize and bind Enzyme..This blocks its activity, thereby preventing the virus from spawning new ones. Virus particlesStops the spread of the virus.

In 2020, researchers at Uppsala University began screening for enzyme inhibitors in collaboration with Scilifelab’s drug discovery and development platform. They used a computer model to identify molecules that could inhibit the activity of the enzyme. This has proven to be a quick way to find a starting point for drug design. Access to Swedish supercomputers has made it possible to evaluate hundreds of millions of different molecules to find molecules that can bind to enzymes. The molecule Next, what was predicted by the model was synthesized and tested experimentally.

“The most promising molecule, like the active substance of Paxlovid, a recently approved combination drug for the treatment of COVID-19, exhibits the ability to inhibit the replication of the new coronavirus. Our molecule itself. Works well with and is also effective against previously identified variants of the molecule. coronavirus“Jens Carlson, an associate professor and lead author of the article, said.
